Windows users finally get native high dynamic range video playback in Firefox without hunting through configuration menus. This change brings a feature that Chrome and Edge have supported for years, closing a long-standing gap in the browser ecosystem. You no longer need to toggle hidden flags to see HDR content on supported displays.
Mozilla ships HDR support for Windows 10 and 11 without manual flags
Mozilla enabled this capability in Firefox version 153 for Windows 10 and Windows 11. The update activates HDR support by default, removing the manual setup steps that previously frustrated users. The browser now handles high dynamic range video streams directly through the operating system's display pipeline.
The feature requires a display that supports the full Windows HDR mode. It does not work with displays that only support 'HDR video streaming' modes. Users should also check for Microsoft's HEVC Video Extensions if they plan to play HDR content encoded in the HEVC (H.265) format. These extensions are often necessary for Windows to decode these specific video streams correctly.
Mozilla is currently preparing display-aware tone mapping, but this feature is not enabled in the current release. The browser also has a limitation where some HDR videos recorded on smartphones in certain orientations may not trigger HDR playback correctly. This detection issue affects specific video files rather than the entire format.
This update completes a basic feature parity step for Firefox on Windows. Users with compatible monitors can now enjoy HDR video without third-party extensions or manual configuration changes. The implementation relies on standard Windows display capabilities to handle the color space conversion.
